A spider is not an insect. It is an animal. It has eight legs and two parts to its body. Because spiders eat insects such as flies, they are useful to people. Spiders live in most countries. They do not live in very cold places like Antarctica and the Arctic. Eight legs Two body parts 2 3 Most spiders have eight eyes but often can’t see very well. They don’t have any bones because their skin is hard. Spiders have fangs to kill their prey. Hard skin Fangs The Huntsman spider has good eyesight so it chases, pounces, and sinks its fangs into the prey. 4 Fangs 5 Spiders live wherever they can find food. They live in the ground, in trees, and in the water. They live on top of mountains where it is cold. Spiders also live in hot deserts. Scorpion spiders are mostly found in deserts. 6 Some spiders live under water. 7 Baby Spiders Spiders are born from eggs. The female spider lays the eggs. She might lay 100 eggs at a time. When the baby spiders hatch, they spin silk lines to fly through the air to a new life. The wolf spider carries her babies on her back. 8 Baby spiders are called spiderlings. 9 Making Silk All spiders make silk inside their bodies. They use their silk to make webs, to make lines to float from place to place, to wrap up their dinner and to make their egg sacs. Some hunting spiders spin a long line of silk across the ground. This “trips up” an insect so the spider can catch it for dinner. 10 The web of this large colorful golden orb spider can be up to three feet wide. 11 Spiders’ Webs Some spiders build webs to catch insects. The spider sits on the web and waits for the insect to fly into the web. The silk in the web is sticky so the insect can’t get away. Because the spider has special hairs on its legs, it doesn’t get stuck when it goes across the web to eat its prey. This spider spins its web upside down. 12 This wasp spider has caught an insect in its web. 13 14 Spiders’ webs are not all the same. If a web breaks, the spider mends it with new silk. 15 Hunting and Eating Spiders that cannot see very well make a web and wait for insects to get stuck in the web’s silk. They cover the insect in silk to eat later. The spider covers the insect in silk to eat later. 16 Spiders with good eyesight don’t make webs. They run after insects and catch them, even big insects, like flies. Spiders also use camouflage to hunt. They sit on a flower or a leaf that is the same color as they are, and pounce when an insect comes by. This crab spider has caught a fly that is twice as big as it is. 17 Keeping Safe Some spiders use camouflage to keep safe. They may look like the flower or branch they are sitting on. This spider is camouflaged on a branch. 18 These spiders are camouflaged in the flowers. Can you see them? 19 The trapdoor spider lives in the ground in a burrow. It makes a door at the entrance to its burrow. The spider uses silk to help the door open and shut. The burrow is a safe place and a place to store food. The baboon spider has hairs on its legs that cause burning pain to its enemies. 20 Trapdoor Spider The trapdoor on this trapdoor spider’s burrow keeps it safe and dry. 21 Special Spiders The biggest spider is the tarantula. Some tarantulas chase and eat birds. They look fierce with their hairy legs and huge bodies. Some spiders inject poison through their fangs to kill their prey. Some can bite people and make them sick, too. The most poisonous spiders live in Brazil and Australia. A tarantula 22 The Brazilian wandering spider is one of the most poisonous in the world. This is the redback spider. It lives in Australia.

  • Spider Bites
    Infectious Disease Epidemiology Section Office of Public Health, Louisiana Dept of Health & Hospitals 800-256-2748 (24 hr number) www.infectiousdisease.dhh.louisiana.gov SPIDER BITES Revised 6/13/2007 Epidemiology There are over 3,000 species of spiders native to the United States. Due to fragility or inadequate length of fangs, only a limited number of species are capable of inflicting noticeable wounds on human beings, although several small species of spiders are able to bite humans, but with little or no demonstrable effect. The final determination of etiology of 80% of suspected spider bites in the U.S. is, in fact, an alternate diagnosis. Therefore the perceived risk of spider bites far exceeds actual risk. Tick bites, chemical burns, lesions from poison ivy or oak, cutaneous anthrax, diabetic ulcer, erythema migrans from Lyme disease, erythema from Rocky Mountain Spotted Fever, sporotrichosis, Staphylococcus infections, Stephens Johnson syndrome, syphilitic chancre, thromboembolic effects of Leishmaniasis, toxic epidermal necrolyis, shingles, early chicken pox lesions, bites from other arthropods and idiopathic dermal necrosis have all been misdiagnosed as spider bites. Almost all bites from spiders are inflicted by the spider in self defense, when a human inadvertently upsets or invades the spider’s space. Of spiders in the United States capable of biting, only a few are considered dangerous to human beings. Bites from the following species of spiders can result in serious sequelae: Louisiana Office of Public Health – Infectious Disease Epidemiology Section Page 1 of 14 The Brown Recluse: Loxosceles reclusa Photo Courtesy of the Texas Department of State Health Services The most common species associated with medically important spider bites: • Physical characteristics o Length: Approximately 1 inch o Appearance: A violin shaped mark can be visualized on the dorsum (top).

Submissions will not be considered unless this form is filled out completely. The proposer is expected to be familiar with the rules, recommendations, and procedures outlined in the “Use and Submission of Common Names” on the ESA website and with the discussion by A.B. Gurney, 1953, Journal of Economic Entomology 46:207-211. 1. Proposed new common name: Four species in the spider genus Cupiennius: 1) redfaced banana spider, 2) spotlegged banana spider, 3) redlegged banana spider, 4) Sale’s banana spider 2. Previously approved common name (if any): none 3. Scientific name (genus, species, author): 1) Cupiennius chiapanensis Medina, 2) Cupiennius getazi Simon, 3) Cupiennius coccineus F. O. Pickard-Cambridge, 4) Cupiennius salei (Keyserling) Order: Araneae Family: Ctenidae Supporting Information 4. Reasons supporting the need for the proposed common name: For the last decade, I have been working on a project involving spiders that have been brought into North America in international cargo. I am in the process of summarizing the work and writing a manuscript. Some of these spiders are huge (leg span 50 to 70 mm) and typically cause strong reaction by cargo processors and produce handlers who discover these creatures when they are unloading and unpacking bananas. One of the spiders, C. chiapanensis, (which has bright red cheliceral hairs – see cover of American Entomologist, 2008, volume 54, issue 2) has caused several misidentifications by qualified arachnologists because 1) this spider was unknown until it was given its scientific name in 2006 and 2) prior to the 21st century, the only reference that many entomologists had to ID international spiders was a children’s book, The Golden Guide to Spiders by Levi and Levi.

  • Tarantulas in the Pacific Northwest1
    WSU Puyallup REC PLS-108 Updated July 2003 Tarantulas in the Pacific Northwest1 Tarantulas (Fig. 1) in the Pacific Northwest? Well, maybe not like the hairy monsters of the tropics, but some very interesting "atypical" species do occur here. Our species belong to the family Antrodiaetidae. One of our most common spiders is the folding-door spider, Antrodiaetus pacificus (Simon). It is a fairly large species, females ranging from 11 to 13 millimeters in length, males slightly smaller. They are generally dark brown to almost black in color with the abdomen purplish brown. Males are characterized by their long legs, slim bodies, and three tergites (hardened plates) on the abdomen. Females (Fig. 2) are more robust with only one tergite. These spiders excavate burrows in the soil or in damp, rotten wood, digging with a row of spines on each chelicer, known as a ratellum. The six to ten inch deep vertical shafts are lined with silk. The webbing extends beyond ground level as a short collar of camouflaged silk. The turret’s two sides may be drawn in by the occupant, forming two "doors" which meet in the middle. At night, Antrodiaetus assumes a foraging posture with its pedipalps and first pair of legs just touching the rim of silk at the mouth of the tube. In this position, the folding door spider can readily detect an insect moving above ground. The spider will leap out of its burrow with lightning speed, seize its victim, and drop back down, like a terrorizing Jack-in-the-box. When finished with its meal, it will add the insect's dry, dismembered body to a silk-covered trash pile at the bottom of its burrow.

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Accidents caused by spider bites occur in many countries and represent a public health problem due to their high severity and occurrence of fatal accidents. In Veterinary Medicine, the incidence of arachnidism is considered nonexistent in large animals, as their thick skin cannot be pierced, rare in cats and common in dogs, particularly due to their exploratory and curious habit, and the habitats of venomous animals, such as the arachnids, located close to urban areas. The aim of this review is to describe the characteristics and distribution of spiders, the mechanism of action of the venom, clinical signs, diagnosis and treatment of accidents caused by arachnids of genera Loxos- celes sp., Phoneutria sp., Latrodectus sp., and suborder Mygalomorphae. Keywords Arachnids, Clinical Signs, Diagnosis, Treatment 1. Introduction Spiders are the second largest order of arachnids, with more than 41,000 species described. Practically all of them are venomous, but only some of them have potential significance to human medicine and veterinary medi- cine, due to their venom toxicity, habitat of species, among other factors [1].

  • Jump Takeoff in a Small Jumping Spider
    Journal of Comparative Physiology A https://doi.org/10.1007/s00359-021-01473-7 ORIGINAL PAPER Jump takeof in a small jumping spider Erin E. Brandt1,2 · Yoshan Sasiharan2 · Damian O. Elias1 · Natasha Mhatre2 Received: 27 October 2020 / Revised: 4 February 2021 / Accepted: 23 February 2021 © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2021 Abstract Jumping in animals presents an interesting locomotory strategy as it requires the generation of large forces and accurate timing. Jumping in arachnids is further complicated by their semi-hydraulic locomotion system. Among arachnids, jumping spiders (Family Salticidae) are agile and dexterous jumpers. However, less is known about jumping in small salticid species. Here we used Habronattus conjunctus, a small jumping spider (body length ~ 4.5 mm) to examine its jumping performance and compare it to that of other jumping spiders and insects. We also explored how legs are used during the takeof phase of jumps. Jumps were staged between two raised platforms. We analyzed jumping videos with DeepLabCut to track 21 points on the cephalothorax, abdomen, and legs. By analyzing leg liftof and extension patterns, we found evidence that H. conjunc- tus primarily uses the third legs to power jumps. We also found that H. conjunctus jumps achieve lower takeof speeds and accelerations than most other jumping arthropods, including other jumping spiders. Habronattus conjunctus takeof time was similar to other jumping arthropods of the same body mass. We discuss the mechanical benefts and drawbacks of a semi- hydraulic system of locomotion and consider how small spiders may extract dexterous jumps from this locomotor system.

Elston, MD arantulas belong to the family Theraphosidae, which contains more than 900 species of T hairy and often very large spiders (Figure). Depending on the species, the tarantula’s body length ranges from 1 to 4 in with 3- to 12-in leg spans. At 12 in, the largest reported species is the Goliath bird- eating spider (Theraphosa blondi). The tarantula’s body consists of 4 pairs of legs that terminate in retractable claws, allowing the spider to grip and climb. Two additional pointed appendages called chelicerae are located just below the eyes and are used to grip food and prey. They contain the venomCUTIS glands that allow the spider to immobilize and kill its prey.1 In addition to the regular hairs that cover the Tarantula. spider’s body, most New World species possess barbed urticating hairs that can be released to defend the spider when it feels threatened.

Chapter 8 HEMOLYMPH AND HEMOCYTES OF TARANTULA SPIDERS: PHYSIOLOGICAL ROLES AND POTENTIAL AS SOURCES OF BIOACTIVE MOLECULES Tatiana Soares, Thiago H. Napoleão, Felipe R. B. Ferreira and Patrícia M. G. Paiva∗ Departamento de Bioquímica, Centro de Ciências Biológicas, Universidade Federal de Pernambuco, Cidade Universitária, Recife, Pernambuco, Brazil ABSTRACT Arachnids compose the most important and numerous group of chelicerates and include spiders, scorpions, mites and ticks. Some arachnids have a worldwide distribution and can live for more than two decades. This is in part due to their efficient defense system, with an innate immunity that acts as a first line of protection against bacterial, fungal and viral pathogens. The adaptive success of the spiders stimulates the study of their defense mechanisms at cellular and molecular levels with both biological and biotechnological purposes. The hemocytes (plasmatocytes, cyanocytes, granulocytes, prohemocytes, and leberidocytes) of spiders are responsible for phagocytosis, nodulation, and encapsulation of pathogens as well as produce substances that mediate humoral mechanisms such as antimicrobial peptides and factors involved in the coagulation of hemolymph and melanization of microorganisms.
